POWER INSTRUMENTATION AMPLIFIER
Single and Dual Versions
DESCRIPTION
The INA126 and INA2126 are precision instrumentation ampli-
fiers for accurate, low noise differential signal acquisition. Their
two-op-amp design provides excellent performance with very
low quiescent current (175µA/channel). This, combined with a
wide operating voltage range of ±1.35V to ±18V, makes them
ideal for portable instrumentation and data acquisition sys-
tems.
Gain can be set from 5V/V to 10000V/V with a single
external resistor. Laser trimmed input circuitry provides low
offset voltage (250µV max), low offset voltage drift (3µV/°C
max) and excellent common-mode rejection.
Single version package options include 8-pin plastic DIP,
SO-8 surface mount, and fine-pitch MSOP-8 surface-mount.
Dual version is available in the space-saving SSOP-16 fine-
pitch surface mount, SO-16, and 16-pin DIP. All are specified
for the –40°C to +85°C industrial temperature range.

DISCHARGE SENSITIVITY
This integrated circuit can be damaged by ESD. Texas Instru-
ments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling
and installation procedures can cause damage.
ESD damage can range from subtle performance degradation
to complete device failure. Precision integrated circuits may be
more susceptible to damage because very small parametric
changes could cause the device not to meet its published
specifications.

APPLICATION INFORMATION
Figure 1 shows the basic connections required for operation
of the INA126. Applications with noisy or high impedance
power supplies may require decoupling capacitors close to
the device pins as shown.
The output is referred to the output reference (Ref) terminal
which is normally grounded. This must be a low-impedance
connection to ensure good common-mode rejection. A resis-
tance of 8Ω in series with the Ref pin will cause a typical
device to degrade to approximately 80dB CMR.
Dual versions (INA2126) have feedback sense connections,
SenseA and SenseB. These must be connected to their respec-
tive output terminals for proper operation. The sense con-
nection can be used to sense the output voltage directly at the
load for best accuracy.
SETTING THE GAIN
Gain is set by connecting an external resistor, RG, as shown:
(1)
Commonly used gains and RG resistor values are shown in
Figure 1.
The 80kΩ term in equation 1 comes from the internal metal film
resistors which are laser trimmed to accurate absolute values.
The accuracy and temperature coefficient of these resistors are
included in the gain accuracy and drift specifications.
The stability and temperature drift of the external gain
setting resistor, RG, also affects gain. RG’s contribution to
gain accuracy and drift can be directly inferred from the gain
equation (1). Low resistor values required for high gain can
make wiring resistance important. Sockets add to the wiring
resistance, which will contribute additional gain error in
gains of approximately 100 or greater.
OFFSET TRIMMING
The INA126 and INA2126 are laser trimmed for low offset
voltage and offset voltage drift. Most applications require no
external offset adjustment. Figure 2 shows an optional cir-
cuit for trimming the output offset voltage. The voltage
applied to the Ref terminal is added to the output signal. An
op amp buffer is used to provide low impedance at the Ref
terminal to preserve good common-mode rejection.

INPUT BIAS CURRENT RETURN
The input impedance of the INA126/2126 is extremely
high—approximately 109Ω. However, a path must be pro-
vided for the input bias current of both inputs. This input
bias current is typically –10nA (current flows out of the
input terminals). High input impedance means that this input
bias current changes very little with varying input voltage.
Input circuitry must provide a path for this input bias current
for proper operation. Figure 3 shows various provisions for
an input bias current path. Without a bias current path, the
inputs will float to a potential which exceeds the common-
mode range and the input amplifiers will saturate.
If the differential source resistance is low, the bias current
return path can be connected to one input (see the thermo-
couple example in Figure 3). With higher source impedance,
using two equal resistors provides a balanced input with
advantages of lower input offset voltage due to bias current
and better high-frequency common-mode rejection.
FIGURE 3. Providing an Input Common-Mode Current Path.
INPUT COMMON-MODE RANGE
The input common-mode range of the INA126/2126 is
shown in the typical characteristic curves. The common-
mode range is limited on the negative side by the output
voltage swing of A2, an internal circuit node that cannot be
measured on an external pin. The output voltage of A2 can
be expressed as:
VO2 = 1.25 VIN – (VIN – VIN) (10kΩ/RG) (2)
(Voltages referred to Ref terminal, pin 5)
–+–
The internal op amp A2 is identical to A1 and its output
swing is limited to typically 0.7V from the supply rails.
When the input common-mode range is exceeded (A2’s
output is saturated), A1 can still be in linear operation and
respond to changes in the non-inverting input voltage. The
output voltage, however, will be invalid.
LOW VOLTAGE OPERATION
The INA126/2126 can be operated on power supplies as low
as ±1.35V. Performance remains excellent with power sup-
plies ranging from ±1.35V to ±18V. Most parameters vary
only slightly throughout this supply voltage range—see
typical characteristic curves. Operation at very low supply
voltage requires careful attention to ensure that the common-
mode voltage remains within its linear range. See “Input
Common-Mode Voltage Range.”
The INA126/2126 can be operated from a single power
supply with careful attention to input common-mode range,
output voltage swing of both op amps and the voltage
applied to the Ref terminal. Figure 4 shows a bridge ampli-
fier circuit operated from a single +5V power supply. The
bridge provides an input common-mode voltage near 2.5V,
with a relatively small differential voltage.
INPUT PROTECTION
The inputs are protected with internal diodes connected to
the power supply rails. These diodes will clamp the applied
signal to prevent it from exceeding the power supplies by
more than approximately 0.7V. If the signal source voltage
can exceed the power supplies, the source current should be
limited to less than 10mA. This can generally be done with
a series resistor. Some signal sources are inherently current-
limited and do not require limiting resistors.
CHANNEL CROSSTALK—DUAL VERSION
The two channels of the INA2126 are completely indepen-
dent, including all bias circuitry. At DC and low frequency
there is virtually no signal coupling between channels.
Crosstalk increases with frequency and is dependent on
circuit gain, source impedance and signal characteristics.
As source impedance increases, careful circuit layout will
help achieve lowest channel crosstalk. Most crosstalk is
produced by capacitive coupling of signals from one channel
to the input section of the other channel. To minimize
coupling, separate the input traces as far as practical from
any signals associated with the opposite channel. A grounded
guard trace surrounding the inputs helps reduce stray cou-
pling between channels. Carefully balance the stray capaci-
tance of each input to ground, and run the differential inputs
of each channel parallel to each other, or directly adjacent on
top and bottom side of a circuit board. Stray coupling then
tends to produce a common-mode signal that is rejected by
the IA’s input.

IMPORTANT NOTICE
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other
changes to its semiconductor products and services per JESD46C and to discontinue any product or service per JESD48B. Buyers should
obtain the latest relevant information before placing orders and should verify that such information is current and complete. All
semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale supplied at the time
of order acknowledgment.
TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms
and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary
to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily
performed.
TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and
applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide
adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or
other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information
published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or
endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the
third party, or a license from TI under the patents or other intellectual property of TI.
Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration
and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered
documentation. Information of third parties may be subject to additional restrictions.
Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service
voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.
TI is not responsible or liable for any such statements.
Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements
concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support
that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which
anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause
harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use
of any TI components in safety-critical applications.
In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to
help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and
requirements. Nonetheless, such components are subject to these terms.
No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties
have executed a special agreement specifically governing such use.
Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in
military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components
which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and
regulatory requirements in connection with such use.
TI has specifically designated certain components which meet ISO/TS16949 requirements, mainly for automotive use. Components which
have not been so designated are neither designed nor intended for automotive use; and TI will not be responsible for any failure of such
components to meet such requirements.
